Using Preliminary Data And Prospective Power Analyses For Mid-Stream Revision Of Projected Group And Subgroup Sizes In Pragmatic Patient-Centered Outcomes Research, Elizabeth A. Tolley Md, Satya Surbhi Md, James E. Bailey Md
Faculty Publications and Presentations
Pragmatic clinical trials are commonly used in patient-centered outcomes research to assess heterogeneity of treatment effects. Patient-Centered Outcomes Research Institute (PCORI) methodology standards for assessing heterogeneity of treatment effects are extremely rigorous, but their implementation in real-world settings can be difficult. Predicting recruitment effectiveness and subgroup characteristics is often challenging and may require mid-stream revision of projected group and subgroup sizes. Yet, little real-world data are available to demonstrate methodologically valid approaches to address situations where such revisions are necessary. These data were used for mid-stream revision of group and subgroup sizes in the Management of Diabetes in Everyday Life …

Diagnostic Accuracy Of Resistive Index Of Capsular And Intratesticular Branches Of Testicular Arteries In Infertile Men With Oligoasthenospermia: A Case-Control Study, Mehdi Zolfaghar-Khani, Hadi Majidi Dr, Behzad Feizzadeh, Mojtaba Sabaghi
BioMedicine
Introduction: Male infertility accounts for nearly 50% of couples' infertility. Only a few studies evaluate the diagnostic accuracy of resistive index (RI) of testicular arteries using color Doppler imaging to identify male infertility. The aim of this study was to investigate the diagnostic accuracy of RI of the capsular and intratesticular branches of testicular arteries in infertile men with oligoasthenospermia and its comparison with normal men.
Material and Methods: In a case-control study, 30 patients with oligoasthenospermia (case group) and 30 healthy controls who meet the inclusion criteria, were selected. For all patients, RI was measured using color …
The Importance Of The Freeway Space In Orofacial Myofunctional Therapy, Robert M. Mason, Honor Franklin, Patricia Grant, Ellen B. Role
The Importance Of The Freeway Space In Orofacial Myofunctional Therapy, Robert M. Mason, Honor Franklin, Patricia Grant, Ellen B. Role
International Journal of Orofacial Myology and Myofunctional Therapy
The purpose of this article is to explain the importance of evaluating and documenting the freeway space (interdental rest position), in initial examinations and at the completion of therapy in patients exhibiting an open mandibular resting position. The freeway space measurements obtained can be shared with parents, patients, and referral sources. To this end, the muscular, neural, and sensory components related to the freeway space are discussed, as well as airway, dental eruption patterns, tactile feedback, and orthodontic relapse considerations. An extraoral method for evaluating the dimensions of the anterior freeway space is proposed.
The Effect Of An Anti-Slip Surface On Objective Measures Of Tongue Strength In Healthy Adults, Nancy Pearl Solomon, Heather M. Clark
The Effect Of An Anti-Slip Surface On Objective Measures Of Tongue Strength In Healthy Adults, Nancy Pearl Solomon, Heather M. Clark
International Journal of Orofacial Myology and Myofunctional Therapy
Purpose: Instrumental assessments of tongue strength have provided clinicians with the ability to obtain quantitative measures to document lingual weakness. A technical challenge with a common instrument is that the surface of the of the bulb-shaped sensor is smooth and can be slippery when contacted by the tongue. This study evaluated whether adding a textured layer to the bulb leads to enhanced strength measures in neurologically normal adults. Methods: Maximum-effort maneuvers for anterior and posterior tongue elevation, right and left tongue lateralization, and tongue protrusion were available from 62 healthy adults using the Iowa Oral Performance Instrument (IOPI). The IOPI …
3d Reconstruction Of Spine Image From 2d Mri Slices Along One Axis, Somoballi Ghoshal, Sourav Banu, Amlan Chakrabarti, Susmita Sur-Kolay, Alok Pandit
3d Reconstruction Of Spine Image From 2d Mri Slices Along One Axis, Somoballi Ghoshal, Sourav Banu, Amlan Chakrabarti, Susmita Sur-Kolay, Alok Pandit
Journal Articles
Magnetic resonance imaging (MRI) is a very effective method for identifying any abnormality in the structure and physiology of the spine. However, MRI is time consuming as well as costly. In this work, the authors propose an algorithm which can reduce the time of MRI and thus the cost, with minimal compromise on accuracy. They reconstruct a three-dimensional (3D) image of the spine from a sequence of 2D MRI slices along any one axis with reasonable slice gap. In order to preserve the image at the edges properly, they regenerate the 3D image by using a combination of bicubic and …

Transcutaneous Energy Transmission: Can We Do It Now?, Yuriy Pya
Transcutaneous Energy Transmission: Can We Do It Now?, Yuriy Pya
The VAD Journal
The percutaneous driveline used in contemporary LVADs presents a continuous risk of infection for the duration of support. Minimizing infection in durable mechanical circulatory support systems requires total implantation of all components and energy transfer by means other than percutaneous drivelines. A novel coplanar energy transfer (CET) system, similar to the original transcutaneous energy transfer (TET) design, is unique by incorporating two large rings with coil-within-the-coil topology to ensure strong resonance power. The CET system consists of an internal integrated controller, a battery coupled with an internal thoracic coil ring, and the LVAD pump. External equipment includes a power transmission …
Can Viruses Cause Lupus?, Stephen I. Reeder
Can Viruses Cause Lupus?, Stephen I. Reeder
Selected Honors Theses
Like so many autoimmune diseases, the exact cause of systemic lupus erythematosus (SLE) remains unknown. Evidence points to both genetics and environment playing roles in the onset of the disease, but neither acts independent of the other. Genetics are the easier of the two to study with recent advances in the field making it easier to isolate genes shared by individuals with the disease. However, genetic studies reveal that there is almost certainly an environmental component to the development of SLE. The underlying pathology and existing research on environmental contributors to the development of SLE suggest that viruses could potentially …
An Approach For The In-Vivo Characterization Of Brain And Heart Inflammation In Duchenne Muscular Dystrophy, Joanne Tang
An Approach For The In-Vivo Characterization Of Brain And Heart Inflammation In Duchenne Muscular Dystrophy, Joanne Tang
Electronic Thesis and Dissertation Repository
Duchenne muscular dystrophy (DMD) is a neuromuscular disorder caused by dystrophin loss—notably within muscles and CNS neurons. DMD presents as cognitive weakness, progressive skeletal and cardiac muscle degeneration until pre-mature death from cardiac or respiratory failure. Innovative therapies improved life expectancy, but this is accompanied by increased late-onset heart failure and emergent cognitive degeneration. Thus, there is an increasing need to both better understand and track disease pathophysiology in the dystrophic heart and brain prior to onset of severe degenerative symptoms. Chronic inflammation is strongly associated with skeletal and cardiac muscle degeneration, however chronic neuroinflammation’s role is largely unknown in …

Longitudinal Clonal Lineage Dynamics And Functional Characterization Of Pancreatic Cancer Chemo-Resistance And Metastasization, Chieh-Yuan Li
Dissertations & Theses (Open Access)
In recent years, technological advancements, such as next-generation sequencing and single-cell interrogation techniques, have enriched our understanding in tumor heterogeneity. By dissecting tumors and characterizing clonal lineages, we are better understanding the intricacies of tumor evolution. Tumors are represented by the presence of and dynamic interactions amongst clonal lineages. Each lineage and each cell contributes to tumor dynamics through intrinsic and extrinsic mechanisms, and the variable responses of clones to perturbations in the environment, especially therapeutics, underlie disease progression and relapse. Thus, there exists a pressing need to understand the molecular mechanisms that determine the functional heterogeneity of tumor sub-clones …

Does A Diagnostic Algorithm Reduce The Overuse Of Chest Ct Angiography In Suspected Pulmonary Embolism? : A Pre- And Post-Intervention Retrospective Study In A Critical Access Hospital, Rattanaporn Mahatanan, Brianna Philbrick, William J. Hirschfeld, Gina Gomez
Journal of Maine Medical Center
Background: Pulmonary embolism (PE) is a common and potentially fatal disease. Although CTA is a gold standard for diagnosis, it carries risks for patients. We sought to minimize the overutilization of chest CTA by implementing a diagnostic algorithm in the hospital to evaluate the likelihood of PE and determine the need for imaging with CTA.
Methods: A retrospective medical chart review was performed for all patients suspicious of PE at Redington-Fairview General Hospital 3 months before and after diagnostic algorithm implementation. Patients who underwent either D-dimer testing or chest CTA were included. Patients were excluded if d-dimer testing was …

Developing An Online Health Community For Autoimmune Disease Patients Through Self-Managed Diet, Rachel Greene
Critical and Creative Thinking Capstones Collection
Part I, Autoimmune Disease Management and the Need for Intervention, discusses current and standard Autoimmune Disease- (AI/AID) management and the shortcomings within. Typical AID-management led by healthcare professionals lacks a holistic, symptom-based approach, thus further contributing to the daily chronic pain of the afflicted. This analysis indicates the need to connect those suffering with AID’s to scientific research that has determined strict dieting can significantly reduce symptoms associated with AID’s. Part II, Synthesizing A Model For Online Health Community Engagement, examines the website prototype of Greenebean, which is an online community developed via user-centric design, in a theoretical, physical, and …
Effects Of Acute Intracranial Pressure Changes On Optic Nerve Head Morphology In Humnans And Pig Model, Sachin Kedar
Effects Of Acute Intracranial Pressure Changes On Optic Nerve Head Morphology In Humnans And Pig Model, Sachin Kedar
Theses & Dissertations
The optic nerve head (ONH) is located at the interface of intracranial and intraocular compartments. It is comprised of lamina cribrosa (LC), a fenestrated connective tissue tethered to the posterior sclera across the scleral canal. Since LC is exposed to intraocular pressure (IOP) anteriorly and intracranial pressure (ICP) posteriorly, it is an ideal site for noninvasively detecting intracranial pressure (ICP) fluctuation. We hypothesized that the pressure differential between IOP and ICP across LC, will determine LC position and meridional diameter of scleral canal (also called Bruch’s membrane opening- BMOD). We tested our hypothesis in 19 human subjects undergoing medically necessary …
Clinically Relevant 3d Characterization Of Simulated Non-Carious Cervical Dental Lesions And The Effects Of Toothbrush And Toothpaste Types On Wear, James Needy
Biomedical Engineering Undergraduate Honors Theses
This study sought to develop a novel method to quantitatively characterize non-carious cervical lesions (NCCLs) using an intraoral scanner (IOS) paired with Geomagic Wrap mesh software. The goal was to compare results with those obtained using an optical profilometer and Proscan superimposition software for clinical application. Comparisons were made using a previously published dataset aimed at measuring tooth loss associated with differing toothbrush and toothpaste types. Results show good comparability between methods and confirm that variation in brush stiffness and paste abrasivity result in significantly and predictably different levels of NCCL development. Extracted human maxillary premolars were assigned to one …

Methods: A multilevel descriptive ecologic study was conducted utilizing electronic medical record data from a large integrated health care system of patients who underwent LUAT from 2013 to 2017. A random sample inclusive of all positive tests was reviewed to investigate geodemographic differences among patients testing positive versus negative. Statistical comparisons …
Ganglioside Detection From Formalin Fixed Human Brain Tissue Utilizing Maldi Imaging Mass Spectrometry, Aaron Harris
Ganglioside Detection From Formalin Fixed Human Brain Tissue Utilizing Maldi Imaging Mass Spectrometry, Aaron Harris
Electronic Thesis and Dissertation Repository
Matrix assisted laser desorption ionization (MALDI) imaging mass spectrometry (IMS) is largely performed on fresh frozen tissue whereas clinical tissue samples stored long term are fixed in formalin, and the fixation process is thought to cause signal suppression for lipid molecules. Studies show that fresh frozen brain tissue sections washed with ammonium formate (AF) solution prior to matrix application in the MALDI-IMS procedure display an increase in signal intensity and sensitivity for lipid molecules while maintaining molecular spatial distribution. Work in this thesis compares MALDI data of ganglioside molecules from fresh frozen and post-fixed rat brain samples, and post-fixed human …

Mechanisms Of Value-Biased Prioritization In Fast Sensorimotor Decision Making, Kivilcim Afacan-Seref
Mechanisms Of Value-Biased Prioritization In Fast Sensorimotor Decision Making, Kivilcim Afacan-Seref
Dissertations and Theses
In dynamic environments, split-second sensorimotor decisions must be prioritized according to potential payoffs to maximize overall rewards. The impact of relative value on deliberative perceptual judgments has been examined extensively, but relatively little is known about value-biasing mechanisms in the common situation where physical evidence is strong but the time to act is severely limited. This research examines the behavioral and electrophysiological indices of how value biases split-second perceptual decisions and the possible mechanisms underlying the process. In prominent decision models, a noisy but statistically stationary representation of sensory evidence is integrated over time to an action-triggering bound, and value-biases …

Stem cell technology has attracted considerable attention over recent decades due to its enormous potential in regenerative medicine and disease therapeutics. Studying the underlying mechanisms of stem cell differentiation and tissue generation is critical, and robust methodologies and different technologies are required. Towards establishing improved understanding and optimised triggering and control of differentiation processes, analytical techniques such as flow cytometry, immunohistochemistry, reverse transcription polymerase chain reaction, RNA in situ hybridisation analysis, and fluorescence-activated cell sorting have contributed much. However, progress in the field remains limited because such techniques provide only limited information, as they are only able to address specific, …

Medical Diagnostics & Translational Sciences Faculty Publications
BACKGROUND: Telomeric DNA is typically comprised of G-rich tandem repeat motifs and maintained by telomerase (Greider CW, Blackburn EH; Cell 51:887-898; 1987). In eukaryotes lacking telomerase, a variety of DNA repair and DNA recombination based pathways for telomere maintenance have evolved in organisms normally dependent upon telomerase for telomere elongation (Webb CJ, Wu Y, Zakian VA; Cold Spring Harb Perspect Biol 5:a012666; 2013); collectively called Alternative Lengthening of Telomeres (ALT) pathways. By measuring (TTAGGG) n tract lengths from the same large DNA molecules that were optically mapped, we simultaneously analyzed telomere length dynamics and subtelomere-linked structural changes at a large …

Prediction Of Molecular Mutations In Diffuse Low-Grade Gliomas Using Mr Imaging Features, Zeina A. Shboul, James Chen, Khan M. Iftekharrudin
Electrical & Computer Engineering Faculty Publications
Diffuse low-grade gliomas (LGG) have been reclassified based on molecular mutations, which require invasive tumor tissue sampling. Tissue sampling by biopsy may be limited by sampling error, whereas non-invasive imaging can evaluate the entirety of a tumor. This study presents a non-invasive analysis of low-grade gliomas using imaging features based on the updated classification. We introduce molecular (MGMT methylation, IDH mutation, 1p/19q co-deletion, ATRX mutation, and TERT mutations) prediction methods of low-grade gliomas with imaging. Imaging features are extracted from magnetic resonance imaging data and include texture features, fractal and multi-resolution fractal texture features, and volumetric features. Training models include …

Improving the data descriptor calculation of crystal’s physical properties requires sophisticated imaging techniques and algorithms. It has been possible to construct 2D population balance models benefiting from characteristic measurements of both crystal’s length and width, compared to the single representative sizes used in 1D models. Our aim is to ameliorate the procedure of determining shape (and not only size) factors, in an automated fashion and directly from the process, for implementation in future models. Here, approaches suitable for real-time applications were employed including engineered imaging sensors and adaptive algorithms. We described the latter in detail for varying 2D image datasets. …
